Alicia Roth Weigel, Sean Saifa Wall and River Gallo are credited as the "cast" of the worthy documentary "Every Body," rather than its subjects - possibly because we get to know these three activists, more than a little bit, over the course of the film. They are introduced on-screen with names, ages and, as is not uncommon these days, pronouns. And then, in introductory interviews by director Julie Cohen (one-half of the team behind the camera for the Oscar-nominated 2018 Ruth Bader Ginsburg doc "RBG"), we learn why they're in a movie about the lives and experiences of intersex people: folks who sometimes possess ambiguous external genitalia, or physical traits of one gender that do not correspond to their sexual DNA. (Typically, XX sex chromosomes determine the female gender, and XY for men, although variations do occur.)
